To an whom it may concern:

Be it known that I, J osnrn F. DONAHUE, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Roofing, of which the following is a specification.

The invention relates to roofing, and has for its object to provide a roofing formed from a plurality of rectangular shaped flexible or pliable shingles, having their edges interlocked in slits of adjacent shingles, said slits at their inner ends terminating in angular disposed slits thereby forming members which will underlie the adjacent shingles and support the manner that the inner edges formed b the slits will be in vertical alignment and the members formed by the slits will support the shingles in-a close joint, and in such a manner that upon pressure on the joints, acute bends will be prevented from being formed in the shingles, therebv obviating breaking or fracturing of the shingles.

' :interengaged and in such a manner as to' A further object is to provide a roofing shingle formed from a plurality of rectangular'shaped pliable shingles, said shingles having two of their converging sides provided with aligned slits, the inner ends of which terminate in slits at substantially right angles to the converging sides, thereby allowing portions of the shingles to be offset when the shin les are interenga'gedl' A further '0 ject is to provide a pliable shingle substantially square in shape, said shingle having extending inwardly from converging sides thereof aligned slits atsubstantially forty-five degrees to the converging sides and terminating in outwardly extending slits at substantially ninety degrees to the sides, said slits allowing the formation of closev joints when the shingles are support the shingles against acutebending under pressure as distinguished from joints formed from enlarged recesses.

With the above and other ob'ects in view the invention resides in the com ination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without-departing from the spirit of the invention.

same in such a In the drawing I Figure 1 is a top plan view of a ortion of aroof formed frominterengaged s ingles. Figure 2 is a detail perspective view of adjacent shingles, showing the interengagement thereof. 7

F1 are 3 is a detail perspective view of the s 1t corner of a shingle, showing 'a portion of'an adjacent shingle inte-rengagexl therewith.

Figure 4 is a detail sectional on'line 44 of Figure 3.

Referring to the drawing, the numeral 1 designates a plurality of rectan lar shaped pliable or flexible shingles 2. he shingles 2 are preferably square, however,- it is to be understood that they may be varied in shape and also in material. The shingles 2 adjacent one of their corners 3 are rovided with inwardly extending aligned sits 4 which extend inwardly at about forty-five degrees to the converging sides 5 of the shingles 2. The inner ends 6 of the slits 4 merge into outwardly extending portions 7 preferably at about ninety degrees to the sides 5 and at substantially a registering angle with -the edge 5 of the adjacent shingles, thereby allowing the portion 8 formed by the slits 4 and 7 to be downwardly ofl'set whenthe adjacent shingle is received. [By soforming the shingles, that is with slits 4 and 7, a more tight, close and water proof joint is provided than is possible where slots are used, as distinguished from slits. By referring to Figure 4, it will be seen that the walls 9 and 10 formed by the slit 4 will be substantially in the same plane and that when pressure is applied on the roofing, for instance by walking over thesame, the portion of the adjacent shingle 2 will not be enlarged recesses, that during the course of manufacture, that a simple die may be employed, and one which is easily This is not the case where enlar recesses are used, as a die is necessary, which is rela-- tively small with parallel cutting edges and view taken a portion of a roof formed from he t sha god rp an angled cutting edge ing shingle is provided, which is simple in slits construction and one which may be easily manufactured and one wherein the dies for forming-theslits are simple in construction,

as distinguished-from dies necessary for cutting slots. It is obvious that-the slits or cuts may be formed by relatively narrow slots, however when the shingles are interengaged the cuts become relatively narrow slots.

The invention having been set forth what is claimed as new and useful is 1,. A roofing formed from a plurality of rectangularly shaped shingles having their corners disposed in alignment transversely and longitudinally of the roof, said shingles having one oftheir corners provided with slits extending inwardly from the converging sides of the corner and merging into extending outwardly towards the converging sides of the corner.

' 2. A roofing formed from a plurality of shingles, said shingles being provided'with corners, the sides of which are at substan tially a right angle to each other, one or said corners being provided with inwardly extending slits for the reception of the sides of adjacent shingles, said slits merging into outwardly extending slits, thereby forming a portion of the shingle adapted to be ofiset from the shingle when the adjacent sides of adjacent shingles are received in the slits.

From the above it will'be seen that a roofand longitudinally of the roof, the sides of adjacent shingles being received in aligned slits extending lnwardly from the converging sides adjacent one corner of the shingles,

said aligned slits being disposed at substantially forty-five degrees to the conver ing sides and merging into outwardly exten 'ng slits at substantially ninety degrees to the converging sides.

4. A shingle formed from pliable material and substantially square in shape, said shingle adjacent one of its corners being provided with inwardly extending aligned slits disposed at substantially forty-five degrees to the converging edges including the corner and merging into outwardly extendin slits at substantially ninety degrees to sai converging edges.

5. A shingle formed from pliable material and substantially rectangularly shaped, said shingle adjacent one 0 its corners being provided with inwardly extending slits merging into outwardly extending slits.

6. A shingle formed from pliable material and angularly shaped, said shingle adjacent one of its corners being provided with inwardly extending straight slits, said straight slits merging into outwardly ex tending straight slits.

7. A shingle formed from pliable material, said shingle being provided with ininto slits extending in a direction out of alignment with the first mentioned slits.

. In testimony whereof I afiix my signature.
